As part of my retraining as an IT specialist and in preparation for the IHK final exam, I completed the module "PC Technology" at my training provider in Hamburg.
PC technology is not considered one of the more demanding basic modules in IT specialist training for nothing. Accordingly, I was delighted that the subject matter was to be taught by our instructor, Mr. Nico Betz, with whom I had already successfully completed the modules "MS Excel" and "Basics of Operating Systems / PC Windows".
Mr. Betz divided the diverse learning material into three scripts, which prepared the extensive and demanding learning material very well and presented it clearly and understandably using slides (with numerous color illustrations). Topics included: Hardware components of a PC, categories of PCs, connections and interfaces, NAS and SAN as well as the most important RAID systems in use and of course many other topics relevant to the exam.
During the lessons, Mr. Betz explained in detail, understandably and very precisely and was thus able to convey the wide range of topics to the group of participants in an excellent way. During the elaboration of the topics, the participants were also involved and through the resulting dialogue, answers could be conveyed even better. This was particularly helpful for us retrainees, because in this way the learning material could be absorbed and structured more easily.
Since the module is full of calculations of all kinds, Mr. Betz attached great importance to the completion of many practical exercises (in individual as well as group work) during the course. The tasks including calculations were discussed in detail after completion. It should be emphasized at this point that Mr. Betz especially trained us course participants to read the tasks very carefully and not to interpret any unnecessary things into them. This is particularly necessary with regard to the final examination at the IHK, as this lack of attention can lead to valuable points being given away in the examination. Topics dealt with here were among other things: Uninterruptible power supply (UPS), calculating data storage volume, calculating printing costs, determining data transfer rates, calculating electrical power / calculating power reserves, RAID systems (e.g. failure rate, net storage capacity), etc.
A special " icing on the cake " was our practical day. We retrainees had the task, together in small groups, to disassemble PCs, identify the individual components, determine the upgrade potential of our system and, of course, at the end everything should be reassembled and functional again. Mr. Betz not only gave us the opportunity to try our hand at classic desktop PCs, but we were also able to use laptops and all-in-one PCs that Mr. Betz (as well as our training provider) had made available to us. The practical day was so well received that even our predecessor group took the opportunity to work hand in hand with us to master the tasks set (due to the Corona measures, our predecessors had to use the home office). It was also very pleasing that the participants supported each other under the professional guidance of Mr. Betz.
Even when there was some tension and unrest within the group during the course of the week, Mr. Betz's level-headed and clear guidance and instructions were able to turn things around and steer the class back on the right course. Mr. Betz succeeded in working through the entire course material with us in the allotted time and even had us work on a few additional bonus tasks that were intended to help us prepare for the exam.
My classmates and I agree that this (nevertheless very demanding module) was a great highlight of the previous retraining to become an IT specialist in application development or IT specialist in system integration. Mr. Betz convinces with his competent, friendly and humorous manner and understands how to convey difficult contents to the course participants in a sustainable way (and independent of their previous knowledge level). Having already completed three modules, I can absolutely recommend Mr. Betz as a lecturer, as my classmates and I have had excellent experiences with Mr. Betz!
With best regards from Hamburg
See you next time and keep up the good work.
